To quote Hubert Farnsworth, of Futurama fame, "Good news, everyone!" The safety's lever is soft enough to do the tweaking Rich mentions. It won't take much to make its two positions crisp and secure. You might first check to see if the lever's retaining pin is still doing its job, and not allowing the part of the lever you don't see to be loose--which condition will also have the same effect. Lugerdoc has oversize pins, or you can use part of the shank from a drill bit that is the appropriate diameter. Don't forget to use non-marring tools/padded vise!
